13 Switching On
► make sure you have a firm and secure stance
► Hold the unit with both hands – right hand on
the handle housing – left hand on the drive
tube.
► Stand upright – hold the unit in a relaxed posi‐
tion and always on right side of your body.
► Do not rest the saw chain and guide bar on
the ground
► Press down the starting lockout lever (1) and
hold it in that position
► Squeeze the trigger switch (2)
14 Switching Off
► Release the trigger switch and starting lockout
lever.
WARNING
Note that the chain continues to run for a short
period after you let go of the trigger switch and
starting lockout lever – flywheel effect.
During longer work breaks – disconnect the plug
from the wall outlet.
When the power tool is not in use, store it in such
a way that it does not endanger others.
Secure it against unauthorized use.
15 Overload Cutout
The unit is equipped with an overload circuit
breaker
which cuts off the power suppy in the event of
mechanical overload due to, e.g.
– excessive infeed force
– "lugging down" the motor
– pinching the saw chain in the cut
If the overload circuit breaker has cut off the
power supply:
► Pull the guide bar out of the cut.
► Wait about 3 minutes for the overload circuit
breaker to cool down.

Do not switch on the unit during this period
because you will otherwise prolong the required
cooling time.
Once the motor starts:
► Run the unit for about 15 seconds off load.
This helps cool the motor windings and con‐
siderably delays renewed tripping of the over‐
load circuit breaker.
16 Operating Instructions
16.1
During Operation
16.1.1
Check the oil level regularly
Never allow the oil tank to run dry.
16.1.2
Check chain tension frequently
A new chain has to be retensioned more often
than one that has been in use for some time.
16.1.3
Chain cold
Tension is correct when the chain fits snugly
against the underside of the bar and can still be
pulled along the bar by hand. Retension if neces‐
sary – see "Tensioning the Saw Chain".
16.1.4
Chain at operating temperature
The chain stretches and begins to sag. The drive
links must not come out of the bar groove – the
chain may otherwise jump off the bar. Retension
the chain – see "Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it is not
slackened off, it can damage the gear shaft and
bearings.
16.2
After Finishing Work
► Slacken off the chain if you have retensioned it
at operating temperature during cutting work.
NOTICE
Always slacken off the chain after finishing work.
The chain contracts as it cools down. If it is not
slackened off, it can damage the gear shaft and
bearings.
